.To all whom it may concern.'

Be it known that l, JOHN ltnsn, a subject of the King ot Norway, residing at Chicago, in the county of @ook and State of illinois, have invented certain new and useful lmprovements in lWheel-Hubsa of which the following is a full, clear, and exact speciication. i

'lhis invention relates to Wheel hubs, and more particularly to Wheel hubs tor detachable Wheels, iinding appli-cation principally, although not necessarily exclusively, in connection with motor vehicles.

The many advantages in having Wheels with quick detachable hubs are becoming more apparent every day, and, as a matter of tact.7 this luxury has become substantially a necessity in connection with motor ve hicles. An automobile driver inds a quick detachable wheel of particular :advantage When one of. the tires has been punctured or exploded` ln case he has an extra Wheel equipped With a tire and has the detaclr able hub arrangement, it is merely necessary for him to detach the injured Wheel and attach the emergency Wheel Without bothering with the repair of the injured tire. Again, detachable Wheels may be interchanged from the rear to the front, and vice versa.

Most of the higher riced cars have quick detachable Wheels. owever, some of the relativelyV inexpensive cars, such, for instance, as the Ford, do not have quick de` tachable Wheels, and, as a matter oit tact, the front and rear Wheels of such cars cannot be interchanged.

Une object of my invention is to provide an arrangement whereby Wheels used on the Ford cars may be made -quick detachable and interchangeable.

JAnother object of the invention is to simplify and improve detachable Wheel hubs.

Another object is to improve means tor locking the portions of the hub against accidental separation.

A 'further object is to provide a hub for detachable Wheels adapted to meet all the requirements for successful commercial operation.

These and other objects are accomplished by providing a Wheel hub having inner and outer members With interlockable portions and novel means for causing an interlocking relation between said membersand locking them in such relationship in a manner to prevent, accidental separation of said monrbers.

rl`he invention is illustrated on the accom panying sheet ot drawings, in a'hiclk- Figure l is alsectional vien' of my iinprove'd wheel hub;

.The various novel features of my invention Will be apparent from the following description and drawings and willbe particularly pointed out in the appended claims.

My present invention finds particular application in connection with Ford Wheels, but not necessarily limited thereto. ln Fig. l l have shown in dotted lines al `ord hub l0. The inner ends of the spokes 11 ot the wheel have been bored out an increased amount and chamtered at 12., and bolted between tWo flange members 13 and 1l, the bolts 15 passing through openings in the flange members 13 and 1-1 and inner ends of the spokes 11 and secured in position by suitable nuts 17. The `llange member 13 is provided With internally and circumferentially arranged serrations 13, mating with externally and circumferentially arranged serrations 19 formed on an inner hub memd ber 2O having a flange 21 which may be secured to the flange 22 of the regular Ford hub by suitable bolts 23. 'lhe outer hub member 13 has formed thereon an annular groove Q4 for the reception ot' the flange member 14. In other Words, the Harige mem- .ber 11 is centered on the outer hub inember 13. ythis langemember 14. is provided with an internal. beveled surface llltl Il tl 5
